The parallel charge boards from Progressive work great! After using them for a couple weekends of flying, I will not go back to charging without them. On mine, the EC5 connector is actually just a tiny bit looser than the standard EC5's that I use on my heli, so the charge lead plugs and unplugs very easily! I don't know if this is by design, or just luck, but it is a nice feature. I hear this question alot, too... so in case you are wondering: It does NOT matter which connectors you use on the board... they are all connected in parallel, so you can use whichever ones are the easiest to plug into =) EG: The top right EC5 connector, and the bottom-left balance connector. Does not matter. Enjoy!!

Works fine and seems to be of very good quality. My only problem with it is that it is very fiddly when loading the board up with 6 5000mah packs. Helps if you have small fingers as there is not a lot of room to get all the power and balance leads all plugged in. Squids are easier to deal with in that respect but not as tidy.

These work great for charging mutiple packs. I charge 6 4s 5000 with my Powerlab 6 no problem. I have bought 4 parallel boards here. If you have questions they get back to quickly and shipping is also very fast. Great products!!

These are rock solid. Eliminates the clutter from multiple parallel wires. I use these in the PRC case and with two iChargers. Great setup. Everyone at the flying field comments on the compact and efficient setup.
